SPECIFICATION forming part of Letters Patent No. 391,498, dated October 23, 1888.

Application filed February 23, 1888. Serial No. 265.082.

To all whom it may concern:

.Be it known that I, J OI'IN HENRY WILEs, a citizen of the United States, residing in the county of Golusa and State of California, have invented a new and useful Road-Scraper, of which the following is a specification.

My invention relates to improvements in that class of scrapers used for making roads, levees, ditches, and all work where earth is to be moved by the use of a scraper, in which jointed levers are used to afford facilities for the proper adjustment of a scraper while loading and unloading. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a detailed View in perspective of the scraper in position for scraping or loading; Fig. 2, a detailed view showing position when unloaded.

Similar letters refer to sim ilar parts throughout the views.

The scraper A can be of several forms, the one shown in the drawings forming no part of my invention. The tongue D is attached to the scraper A by the tongue-braces D, with a hinged joint at t, which allows the scraper to swing to any desired angle. The forward ends of the braces D are bent downward, forming two lugs, to which are attached thelever-plates F by a loosefitting bolt passing through the lugs on the under side of the tongue. The lever C is secured between the plates F by bolts, as shown in the drawings. The plates (N0 model.)

[ Fare bent downward at their rear ends, forming lugs similar to the lugs of the braces D. To these lugs is attached a connecting-rod,E, which is forked at either end, the forward end receiving thelugs ofplates F and the backward end engaging with circular plate G, which is provided with several holes for the adjustment of the scraper to any desired angle. To the end of the lever O is attached a cord, H, for the purpose of drawing down the lever after the scraper is dumped or unloaded.

In operating, the scraper is adjusted to an angle to suit the nature of the earth to be cut or scraped, with the lever 0 down, as shown in Fig. 1. The weight of the lever in this position prevents it from rising. As soon as the scraper is loaded or arrives at the place of deposit, by raising the lever the scraper will dump or unload and will be in the position shown in Fig. 2.

What I claim as myinvention,and desire to secure by Letters Patent, is-

l. The lever (l, in combination. with the plates F and tongue-braces D, substantially as set forth.

2. The connecting-rod E, the circular plate G, in combination with plates F, lever O,

scraper A, and tongue B, substantially as described.
